Hart was the board member charged with vetting new Yahoo CEO Scott Thompson before he was hired.

Thompson was caught last week having misleading information in his bio for the past 8 years.

It said he had a computer science degree when he does not.

Theoretically, Hart should have checked up on every detail in Thompson's public and private bios to make sure it was all true.

The resume scandal started when Yahoo activist shareholder Dan Loeb wrote a letter about it last Thursday. The letter also accused Hart of lying about her education. It turns one of the degrees she said she had was actually just a concentration in her major.

If Yahoo thinks Hart's exit will end the scandal, it has another think coming.

Thompson still owes shareholders, employees, and the board a clear explanation as to why misleading information was on his bio in the first place AND why he didn't deny that he had a CS degree during a radio interview in 2009.
